Limiting the memcpy to be the sizeof(struct rndis_message) can
truncate the message if there are Per-Packet-Info or Out-of-Band data.

In my earlier patch (commit 45326342), the unnecessary kmap_atomic and
kunmap_atomic surrounding this memcpy have been removed because the
memory in the receive buffer is always mapped. This memcpy is not
necessary either. To fix the bug, I removed the memcpy.

Well, where the heck is patch 2/2?

It's still in the mail server's send queue. This happens sometimes on our mail server.
But it should reach you in half hour or so...
